CONTRALATERAL ABOLITION OF ESSENTIAL TREMOR FOLLOWING A PONTINE STROKE

A 90-year-old man with a longstanding bilateral essential tremor prese nted with right-sided weakness of sudden onset. The CT scan of the bra in showed a hypodense area in the left side of the pens consistent wit h an infarction. The paralysis disappeared without recurrence of the t remor on the right, but the tremor persisted on the left. It is likely that the fronto-rubro-spinal pathway had been interrupted at the leve l of the pens abolishing the tremor on the right side. (C) 1997 Elsevi er Science B.V.
